Thought this info might help someone else. The RV park that we are in now has cable and internet hookups. Leon tried for several hours to hook up the internet in the interior of the Monty. The Cox cable guy told him that the cable and internet have to be split on the outside of the trailer and two cables brought into the trailer. He said that is the only way it will work in these trailers. He put the internet connection in through the phone hole. (My technical term). Works great.
This forum has been a big help and encourgement to us newbies.
